The Southern Proper Motion Program IV. The SPM4 Catalog
T. M. Girard, W. F. van Altena, N. Zacharias +8
We present the fourth installment of the Yale/San Juan Southern Proper Motion Catalog, SPM4. The SPM4 contains absolute proper motions, celestial coordinates, and (B,V) photometry…
Proper Motion Study of the Magellanic Clouds using SPM material
Katherine Vieira, Terrence Girard, William van Altena +6
Absolute proper motions are determined for stars and galaxies to V=17.5 over a 450 square-degree area that encloses both Magellanic Clouds. The proper motions are based on photogra…

The third US Naval Observatory (USNO) CCD Astrograph Catalog, UCAC3 was released at the IAU General Assembly on 2009 August 10. It is the first all-sky release in this series and c…
Space Velocities of Southern Globular Clusters. V. A Low Galactic Latitude Sample
D. I. Casetti-Dinescu, T. M. Girard, D. Herrera +3
We have measured the absolute proper motions of globular clusters NGC 2808, 3201, 4372, 4833, 5927 and 5986. The proper motions are on the Hipparcos system and they are the first d…
